Burkholderia terrae sp. nov., isolated from a forest soil.

A Gram-negative, slightly curved rod-shaped bacterium, designated strain KMY02T, was isolated from a forest soil in Daejeon, South Korea. On the basis of 16S rRNA gene sequence similarity, strain KMY02T was shown to belong to the family Burkholderiaceae of the Betaproteobacteria, and to be related most closely to Burkholderia hospita LMG 20598T (98.7%), Burkholderia caribensis LMG 18531T (98.0%) and Burkholderia phymatum LMG 21445T (97.4%). Its phylogenetic distance from all recognized species within the genus Burkholderia was less than 97%. Chemotaxonomic data [Q-8 as the major ubiquinone; C16:0, C17:0 cyclo, summed feature 7 (C18:1omega7c/omega9t/omega12t) and C15:0 as the major fatty acids] supported the affiliation of strain KMY02T to the genus Burkholderia. The results of DNA-DNA hybridization experiments and physiological and biochemical tests allowed genotypic and phenotypic differentiation of the strain from recognized Burkholderia species. Therefore, KMY02T (=KCTC 12388T=NBRC 100964T) represents the type strain of a novel species, for which the name Burkholderia terrae sp. nov. is proposed.
